Our take
Most power banks are phone toys. The 737 is the one we pack when a MacBook Air also needs a bump. Wattage is the spec that matters. Capacity is second. Brand trust is third — cheap unlabeled packs are how people learn about airport bin lectures.
Read the airline rule on the box. If you only charge earbuds, buy a smaller Anker and save the weight.
